Zenith "Advance" Transistor (Body) Hearing Aid

The Zenith "Advance" transistor body-style hearing aid was manufactured by the Hearing Aid Division of the Zenith Radio Corp. in 1960. It contained 4 transistors.

The Zenith "Advance" measured 2⅝" x 1¾" x 11/16" (6.7 x 4.5 x 1.8 cm), and weighed 1.5 oz. (44 g) without the battery.

Here is a blurb for the Zenith "Advance". Note that it sold for $90.00 in 1960.
